    What we say about thermal curtains

    • All our made to measure curtain fabrics are available with a thermal lining
    • This heavy lining helps to reduce heat loss through your windows and doors by 14%
    • Team thermal linings with naturally thicker curtain fabrics, like velvet, to improve their thermal qualities.
    • Thermal lined curtains pair wonderfully with Voiles. The sheer voile fabric will gently filter the light while providing daytime privacy and the insulated curtains will help keep your room snug at night.

    Save on curtains

    Refresh your space and bring colour and pattern to any room. Thermal linings help keep the heat inside the room and are available with all our curtains.

    Tips for thermal curtains

    A wave header is a good option for wide windows and doors, providing floor to ceiling coverage for less draughts.

    If your radiator sits underneath your window, go for curtains that finish just below the sill.

    Layering at your window can keep your room even more snug. Try a thermally-lined Roman blind or one of our ThermaShade™ or Duette® blinds.

    There’s a time and place for DIY

    Don’t risk getting it wrong at your windows. With measuring and fitting always included for a fabulous finish, we’ll help you get the look you want, without the hassle.

    Questions on our curtains?

    Here are some of our frequently asked questions (FAQs) about our thermal curtains. If you have a question about our service or your appointment, please see our general FAQs.

    What are thermal curtains?

    Thermal curtains are made with an extra lining that helps to reduce heat loss through your windows. This thermal lining is a fabric with a single acrylic coating that reduces the amount of heat which can be lost by transmission through the fabric. Thermal linings offer a fuller appearance, and plenty of practical benefits like extra privacy, plus they help to reduce fading and to block incoming light too.

    Are thermal curtains good for summer?

    Thermal curtains aren't just for keeping your home warm in winter, they'll also help to keep things cool in summer. In the same way they reduce the amount of heat that escapes through windows when it's cold, thermal curtains can also prevent heat from entering a room when outdoor temperatures are high, making them a great all year round solution to keep your home comfortable.

    Can you machine wash thermal lined curtains?

    All of our curtain fabrics are dry clean only, but there are plenty of ways to keep your thermal curtains fresh for longer. The easiest way to clean your thermal curtains is to use the soft brush attachment of your vacuum cleaner, designed for furniture and upholstery. A hand held steam cleaner can also be used to remove any creases or wrinkles. Our curtains cleaning guide contains more handy hints on caring for your thermal curtains.

    Do thermal curtains keep cold out and save on energy bills?

    Thermal curtains add an extra layer of insulation to your windows so they're a great way of stopping heat from escaping and cold air from coming in. We'll make your curtains to the exact dimensions of your window so you'll get a good coverage all around the frame to help stop draughts getting in through any gaps. For maximum impact, make sure you close your curtains as soon as the sun goes down to keep your room warm.

    Do thermal curtains cause condensation?

    The likelihood of condensation at your windows depends on a few factors like the indoor temperature, outdoor temperature and humidity levels. If indoor humidity levels are high and warm moist air comes into contact with a cold surface, condensation may occur. Thermal curtains can potentially contribute to this if they prevent warm indoor air from reaching the windows. Adequate ventilation is crucial to control indoor humidity levels so make sure you allow some air circulation around your windows by slightly opening curtains or blinds during the day.

    How do I attach a thermal lining to my curtains?

    Our seamstresses will make your choice of curtain fabric with a thermal lining, so you don’t need to worry about this. Simply discuss your requirements with your local advisor and we’ll do it all for you. Measuring and fitting is all included in the price too. Book your appointment to find out more.
